Problems solved by technology

Therefore, if one of the disks has an inconsistent connection level with the master controller and the slave controller, data access errors between the master and slave controllers will occur, making it impossible for the master and slave controllers to provide mutual backup functions

Embodiment Construction

[0022] The present invention is a system and method for judging the disk connection level of double backup storage. The following describes the preferred embodiment of the disk connection level judgment system of the present invention with the icons, and then applies the method and technology of the present invention to describe in detail the step flow of the disk connection level judgment method of the present invention.

[0023] figure 1 It is a schematic diagram of the judging system of the disk connection level of the dual backup memory of the present invention. As shown in the figure, the disk connection level judgment system 100 of the dual backup memory of the present invention is applied to a dual backup memory having a master controller 110, a slave controller 120, and a disk group 130. The master controller 110 and the slave controller 120 are central controllers of the master and slave relationship generated according to a predetermined rule in the dual backup memory, ...

Abstract

The invention relates a system and a method for judging the disk connecting level of a double-backup memory, mainly applied in memories of master and slave controllers with double backups. Random numerical values are written in sequence through each disk in a disk group and are read out for interpretation so as to judge whether the connecting sequences that each disk in the disk group is connectedto the master and the slave controllers are consistent or not.

Description

Technical field [0001] The present invention relates to a system and method for judging disk connection levels, and in particular to a technology used in the storage of master and slave controllers with dual backups to judge the disk connection levels. Background technique [0002] In data storage technology, Just a Bunch of Drives (JBOD) connects multiple hard disks to a central controller at the same time to form a virtual disk with a larger capacity. Because the total capacity of the linear stretch disk group (JBOD) is the sum of all the constituent hard disks, it can meet the demand for large amounts of storage. However, when using JBOD to store data, the data is scattered and stored on physical disk drives, so the efficiency of data access can be improved, and it is especially suitable for storing larger-capacity data. . However, JBOD does not have the function of avoiding hard disk damage. [0003] Therefore, if you want to store important data that needs to be protected, ...
